INKING MECHANISM FOR PRlNTlNG MACHlNEs.

SPECIFICATION forming part of Letters Patent No. 716,089, dated December16, 1902.

Application filed March 1.1900. Serial No. 6,938. on model.)

Be it known that I, THOMAS M. NORTH, a

subject of the Queen of Great Britainand Ireland, residing at New York,county of Kings,

and State of New York, have inventedcertain new and useful Improvementsi n InkingMechanism for Printing-Machines, fully described andrepresented in the following specification. and the accompanyingdrawings, forming a part of the same.

This invention relates to certain improvements in inking mechanisms ofprinting-machines.

In order to successfully operate printingmachines, it is well understoodthat the ink must be thoroughly and intimately mixed,

broken up, and distributed on the rollers of theinking mechanisms beforeit is applied to the forms. To accomplish this result, it has beencustomary to allow the machines to run with the printing-couples inoperation for a longer or shorter period of time, the impressions whichare produced before the-ink on the inking mechanisms is brought into theproper condition being thrown away. If, however, the machine is allowedto run until the ink is brought into exactly the right condition, aconsiderable quantity of paper is wasted. i

. One of the objects of this invention is to pro-' duce aprinting-machine in which the print ing mechanism and theinkingmechanism are independently driven, so that it is possithrough theseveral rollers thereof without running the remainder of the machine.

A further object of this invention is to produce a printing-machineemploying a plural ity of couples in which all the couples shall bedriven from one train of mechanism and the inkingmechanismsifor theseveral couples shallbe driven from another train of mechanism, so thatit may be possible to operate all the inking. mechanisms of the ma-:chine for the purpose of inking up without driving any of theprinting-couples.

A further object of the invention is to produce an improved form ofinking mechanism in which the form-rollers can be moved away ess-ofinking up.

. A further object of the invention is to produce a printing-machineemploying a plurality of printing-couples and a plurality of inkingmechanisms in which the couples are driven by one mechanism and theinking mechanisms by another mechanism, devices being provided of such acharacter that the inking mechanism of any of the couples may be movedaway from the path of the formcarrier of the couple.

A further object of the inventionis to produce a printing-machineemployinga pluralityof printingcouples and a plurality of inkingmechanisms in which the couplesshall be driven from one mechanism andthe inking mechanisms from another mechanism and in which by suitableconnections it shall be possible to simultaneously move the formrollersof all the inking mechanisms away from the path of the several formcarrie rs.

With these and other objects in view the invention consists in certainconstructions and in certain parts, improvements, and combinations, aswill be fully described in the following specification and thenspecifically pointed out in the claims hereunto appended.

In the accompanying drawings, which form i a part ofthis specification,and in which like characters of reference indicate the same parts,Figure l is a sectional side elevation of the machine, taken on the line1 l of Fig. 2 and looking in the direction of the arrow in that figure.of the frame being shown in section.

Fig. 2 is a plan view, a portion Fig. 3 is a vertical cross-section onthe line 3 3 of Fig. 1. Fig. 4 is a detail side elevation of the ,twoend couples of the machine, illustrating more particularly the means formoving the inking-rollers away from the form-cylinders.

The machine which has been selected to illustrate a concrete embodimentof the invention is a rotary multicolor-machine, preferably printingfrom planographic surfaces and adapted to print one color on one side ofthe web and two colors on the other side.

is to be understood, however, that the invention is not limited tomulticolor-machines nor to machines employing planographic surfaces.

Referring to said drawings, 1 and 2 indicate the usual side frames, inwhich the several. shafts of the machine are journaled, the bearings forthe shafts being of any usual or desired form. The couple-which printsupon one side of the web is shown at the left-hand end of the machine,said couple consisting of a form-cylinder 3, mounted on a shaft 4, andan impression-cylinder 5, mounted on a shaft 6. After being acted uponby this couple the web passes around the surface of a largeimpression-cylinder 7, mounted on a shaft 8. In the machine shown aplurality of formcylinders cooperate with this large impression-cylinder7, and while anynumber of such cylinders may be employed in the presentconstruction two such cylinders are showna form-cylinder 9, mounted on ashaft 10, and a form-cylinder 11, mounted on a shaft 12.

In machines constructed in accordance with the invention independentdriving mechanisms are provided for the printing-couples and the inkingmechanisms. While the driving mechanism for the printing-couples may bevariously constructed and arranged, in the present machine a power-shaft13 is provided, said shaft being provided with any suitable drivingdeviceas, for instance, a belt-pulley 14. This shaft 13 extends fromside to side of the machine and is journaled in suitable hearings in themachine-frame. It carries on the end opposite the pulley a gear 15, saidgear being secured to the shaft in any suitable manner, as by a key 16.The gear 15 meshes with a gear 17, said gear being secured in anysuitable manner, as by a key 18, to a counter-shaft 19, which alsoextends through the machine from side to side and is parallel with thepower-shaft 13. The counter shaft 19 is extended through the side frame1 and carries on its projecting end a gear 20, said gear being arrangedto run loosely on the shaft 19, but being capable of being securedthereto in any suitable man- While the construction by which the gear 20is secured to the shaft may be varied, in the machine herein shown thehub 21 of the gear 20 forms a part of a clutch, the cooperating partconsisting of a notched sliding collar 22, which is secured to the shaft19 by a feather 23 orin any other suitable manner. As is usual in suchconstructions the sliding collar 22 is provided with a groove 24,whichis engaged by pins 25,said pins being carried on a yoke 26. This yoke 26has an upward extension 27, which forms a handle, and a lower extension28, (see Fig. 3,) which is pivoted, by means of apin 29, between cars30, secured to the under sideof the side frame 1. The gear 20 mesheswith a gear 31, whichis secured to the cylinder-shaft 8 in any suitablemanner, as by a key 32. The gear 31 meshes with a gear 33,which issecured to the shaftl2 in any suitable manner, as by a key 34. The gear31 also meshes with a gear similar to the gear 33, which is secured tothe shaft 10. This gear is not, however, shown in any of the figures, itbeing located directly under the gear 33 and is of the same size as saidgear.

.The gear 31 further meshes with a gear 35,

which is secured, by means of a key 36 or in any other suitable manner,to the shaft 6 of the impression cylinder 5. The gear 35 meshes with agear 37, which is secured by a key 38 or in any other suitable manner tothe shaft 4 of the form-cylinder 3.

From the construction so far described it is obvious that when power isapplied to the main shaft, as by a belt,and the clutch-collar 22 is inengagement with the hub 21 of the gear 20 the power-shaft will drive themembers of the several couples through the train of gearing which hasbeen described. When, however, the clutch collar is disengaged or throwninto the position shown in Fig. 2, the power-shaft will rotate withoutrotating the members of the couples, since the gear 20, which is looseon the shaft 19 and which serves as the transmitting-gear from thisshaft to the train, willnot be rotated by the shaft.

As has been before stated, an independent mechanism is provided fordriving the inking mechanisms which supply ink to the several couples.While this driving mechanism may be variously constructed and arranged,in the machine shown the gear 17, which has been before described askeyed to the shaft 19, is arranged to mesh with a large gear 39, whichis loosely mounted on the shaft 8 of the large impression-cylinder 7,the construction being clearly shown in Fig. 1. The gear 39 meshes withtwo gears 40 and 41, mounted on the shafts 10 and 12, respectively, andalso with a gear 42, mounted on the shaft 6. The gear 42 meshes with agear 43, mounted on the shaft 4, before referred to. 40, 41, and 43 runloosely on the shafts 10, 12, and 4, respectively, and it may be hereremarked that while it is convenient to mount these gears on the shaftsin the manner described they might be mounted in any other suitablemanner-as, for instance, on studs projecting from the sides of theframe--the object being to provide a train of gearing for driving theinking mechanisms which is independent of that which drives theprintingcouples.

As has been stated, the purpose of the gears 40, 41, and 43 is toprovide a driving mechanism for the inking devices to be hereinafterdescribed. While these gears may be arranged to drive the inking devicesin any suitable manner, in the construction shown the gear 40 hassecured thereto a gear 44, said gear being shown as slightly less indiameter than the gear 40 and being secured thereto by bolts 45. In thesame manner The gears by bolts 47, and the gear 43 has asimilar gear 48secured to it by bolts 49.

Three groups of inking mechanisms are shown, one for each of theform-cylinders 3, 9, and 11. These inking mechanisms may be of any usualor desired construction. In the machine shown they comprise fountains50, provided with fountain-rolls 51. The inkis delivered from thesefountain-rolls 51 by means of doctors 52-the operating mechanisms ofwhich are not shown, as they may be of any ordinary formtodistributing-rolls 53. Cooperating with the rolls 53 are groups of rolls54, these rolls serving to mix, break up, and distribute the ink in theordinary manner. The rolls 53 are driven rolls, the shafts of theserolls being provided with gears 55, which mesh with intermediates 56,which are mounted on studs 57, extending from the side frames 2. Theseintermediates 56 mesh with the gears 44, 46, and 48, respectively, therolls 53 being driven in the manner described to drive the rolls 54 byfriction, as iscommon in such constructions.

Cooperating with the rolls 53 are transmitting-rolls 58,of which two areshown, these rolls serving to distribute the ink from the rolls 53 toauxiliary distributing-rolls 59, of which two are shown. These rolls 59are mounted on shafts 60, which are journaled in the side frames, andthese shafts 60 are provid'edat one end with gears 61, said gearsmeshing with intermediates 62, which are mounted on studs projectingfrom the side frames 2. The intermediates 62 are in mesh with the gears44, 46, and 48. It is apparent, therefore, that the rolls 59 are drivenrolls. Each of these rolls59 delivers its ink to a group ofform-rollers, of which two (marked 63 and 64) are shown, these rollersbeing mounted on shafts 65 66, respectively.

' Each group of form-rollers 63 64 is mounted so as to be movable towardand away from the path of movement of the forms and will in theconstruction shown be held away from the said path of movement until theinkingup operation is completed. While the rollers may be mounted andlocated in various ways so as to effect this result, preferably and asin the machine shown the shaft is mounted in bearings 67, which arecarried on blocks 68. These blocks 68 are mounted on projections 69,which are secured to, preferably by being formed in one piece with, arms70, the said arms being supported on the shafts 60 ofthedistributing-rolls 59. In the same manner the shaft 66 of the rollers64 are mounted in bearings 71, said bearings being mounted on blocks 72.These blocks 72 are secured to projections 73, which are secured to,preferably by being formed in one piece with,arms 74, which are alsomounted onthe shafts 60. The blocks 68 and 72 are preferably adjustablysecured tothe projections 69 and 71, this being effected in any suitablemanner. In the construction shown each block is provided with a slot75,through which passes a bolt 76, the construction being a usual one.

It willof course be understood that there are two of the arms 70one ateach side of the machine and two of the arms 74one at each side of themachine-and it will be further seen that by swinging the arms 70 74around the shafts 60 as centers the form-rollers 63 64 will be movedtoward and away from the path of travel of the forms on theformcylinders and that this movement will be effected without moving therollers 63 64 out of contact with the rolls 59.

Any suitable means may be employed to give the arms 70 74 the swingingmovement referred to. In the machine shown two disks 77 are provided foreach couple, one of these disks being located on each side of themachine for controlling the movement of the arms 70 74 of one of thegroup of form-rollers 63 64, and two cam-disks 78 are provided one oneach side of the machine'for controlling the movement of the arms 70 74of the other group of form-rollers. The disks 77 are mounted on studs79, projecting from the side frames of the machine, and the disks 78 aremounted on studs 80, similarly supported. Each of these disks 77 78 isprovided with two eccentric or cam slots 81 82, these slots beingengaged by pins or rollers 83 84, carried on the arms 70 74,respectively. It is apparent, therefore, that the disks constitute camsand that by rotating them the arms 70 74 will be moved about the shafts60 as centers, and the rollers 63 64 will be given the swinging movementbefore referred to.

Any suitable means may be provided for giving the disks the rotatingmovement before referred to, which, it may be remarked, is preferably,though not necessarily, a simultaneous movement. While the means bywhich this simultaneous movement may be given to all the sets of disksmay be varied widely, in the machine shown each of the disks 77 isprovided with a segment 85 and. each of the disks 78 with a segment 86.Each pair of disks 77 78 is arranged to mesh with a movable segment.Three such segments are provided on each side of the machine, thesesegments being marked 87 88 89. The segments 87 have projecting fromthem arms 90, and the segments 88 have projecting from them arms 91 92,and the segments 89 have projecting from them arms 93. The arms 91 ofthe segments 88 have connected to them. links 94,saidlinks beingprovided with hooked ends 95, which take over pins 96 on the arms 90, sothat the two arms are connected for simultaneous movement. The hooks areclosed, however, by pins 97, and when said pins are withdrawn the bookswill be released, so as to disconnect the segments 8788. The arms 92 areconnected to the arms93by means of links 98, said links having hookedends 99, closed by pins 100, which take over pins 101 on the arms 92.

With the construcin or out, as the case may be.

Any suitable means may be provided for moving either pair of disks.Preferably, however, and as in the machine shown there is provided ashaft 102,which extends across the machine from side to side and isprovided at each end with segments 103, said segments meshing withsegments 10%. These segments 101 are in the construction shown connectedto the segments 88. The shaft 102 is further provided withhandle-sockets 105 on each side of the machine, to which sockets areconnected handles 106. With this construction it is apparent that bymoving either of the handles 106 the form-rollers of each inkingmechanism may be moved toward or away from the path of the forms carriedon the form-cylinder.

It may happen under certain circumstances that it is desirable todisconnect the inking mechanism of any one of the couples from that ofthe other couples and to operate said inking mechanism separately. Tothis end each of the segments 87 is provided with 'a handle 107, one ofthese handles being of course located on each side of the machine. Inthe same way the segments 88 are provided with handles 108, and thesegments 69 are provided with handles 109. If, for instance, it isdesired to operate the inking mechanism which is controlled by thesegment 87 independently of the other mechanisms the links 94 aredisconnected from the pins 96, thus disconnecting the segments 87 fromthe remaining segments. By operating handles 107 either simultaneouslyor independently the inking mechanism for that couple will be thrownout.

The operation of the machine will be readily understood without furtherdescription.

It is to be understood that the mechanisms by which the invention iscarried into effect may be widely varied. The invention is not,therefore, to be limited to the specific details of constructionhereinabove described.
